An ONJN-licensed Romanian casino with a large bonus and card-only payments
Visit Bilion Casino →Bilion Casino welcome bonus in Romania
Context for Romania: Romania's check runs the opposite way to most people's instinct, and getting it backwards is the common mistake. The ONJN publishes both a blacklist of unlicensed domains and a WHITE LIST of licensed operators - Class I for operators, Class II for suppliers - and only the white list makes play lawful. A site being absent from the blacklist proves nothing: you will probably still be able to reach it, but playing there is unlawful unless it appears on the white list. The blacklist is large and actively enforced - 1,546 domains have been ordered blocked by ISPs, and Polymarket was added on 29 October 2025. Check any operator against the Class I list at onjn.gov.ro before depositing rather than trusting a licence badge or an affiliate page, this one included. The market is also tightening fast: Law 141/2025, in force from 1 August 2025, raised the annual authorisation tax from 21% to 30% of gross gaming revenue and the minimum annual fee from EUR 400,000 to EUR 480,000; operators need a permanent establishment in Romania and, where their servers sit abroad, mirror servers on Romanian soil giving ONJN real-time access. Advertising rules are moving too - celebrity and influencer endorsements are already banned across TV, radio and social media, Bucharest is removing gambling publicity from city-controlled outdoor sites from 1 January 2026, and the regulator's 2026 agenda proposes raising the gambling age from 18 to 21 plus restricting online promotions between 06:00 and midnight.

Our verdict
Bilion Casino is a genuinely ONJN-licensed Romanian casino, operated by Deep Games S.R.L. under Class I licence L1234008W001473, valid until February 2033 - corroborated across independent sources including the company's CUI registration details. It's part of a disclosed multi-brand family, with the same licence covering sister casinos Million Casino and Prima Casino. The game library is substantial - reported between 1,000 and nearly 1,900 titles depending on source - from 19-plus established providers, with a standout live blackjack section spanning more than 80 tables after Pragmatic Play Live integration resolved earlier live-casino gaps some older reviews flagged. The welcome package is large on paper, up to RON 35,000 plus 275 free spins across four deposits per our own sourced figure, though other independent reviews cite slightly different numbers (30,000 RON plus 250-300 spins) - these promotions appear to be actively adjusted, so confirm the live terms before depositing. The clearest limitation is payments: Bilion Casino only accepts Visa and Mastercard for deposits, with no alternative methods at all - a real constraint some players specifically criticise, alongside occasional complaints about website performance. Withdrawals process on the operator's side instantly but typically take up to 24 hours to actually land in your account. A legitimately licensed Romanian casino with a genuinely large bonus and deep game catalogue, held back mainly by its narrow payment options.
